CONNECTICUT, A CORPORATION OF WRENCH-HANDLE.

SPECIFICATION forming part of Letters Patent No. 705,451, dated Ju1y22,1902.

Application filed May 9 ,1902. Serial. No. 106 ,588. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD H. SEARS, a citizen of the United States ofAmerica, residing at Collinsville, in the county of Hartford, and Stateof Connecticut, have invented certain newand usefullmprovementsinWrench-Handles, of which the following is a specification.

The object of the improvement is the production of an improvedwrench-handle having certain features of novelty and advantage.

In the accompanying drawings, Figure 1 is a front or face View of awrench embodying said improvement with features of interior constructiondenoted by dotted lines. Fig. 2 is a side view of the same wrench withfeatures of interior construction denoted by dotted lines. Fig. 3 isaview ofthe Wrench in horizontal cross-section on the plane a; 00. Fig.I is a view of the wrench in horizontal cross-section on the plane 1 y.Fig. 5 is a view of a modification of the nut-collar at the lower end ofthe wrench-handle.

In the accompanying drawings the letter (1 denotes the wrench-bar; b,the wrench-head; c, the movable jaw; d, the operating-screw, and e therosette, by which the operatingscrew is rotated.

The letter f denotes the step-plate,which is supported by theferrule-nut g. This is a nut which has a depending ferrule embracing theupper end of the handle h, which is preferably of wood.

The letter 70 denotes the shank attached to the wrench-bar and insertedthrough the handle h. On its lower end it takes the nut-collar 'L, whichbears on its upper side a part 2', which enters and centers the handle,as shown in Figs. 1 and 2, or, as modified in Fig. 5, it may be soshaped as to embrace and center the handle. The shankisnon-cylindricalin shape and preferably that end is attained by slabbing ofithe sides asshown by dotted k in Fig. 3. The hollow interior of the handle is alsonon-cylindrical, and preferably that end is attained by means ofgrooves, as illus vtrated in Fig. 4:.

The letter m denotes soft metal, preferably type-metal, which makescontact with the exterior of the shank and with the interior of thehandle. It is poured into place in a molten condition and allowed tocool and solidify. This use of the soft metal gives the wooden handle afirm bearing and support upon the metallic shank fromend to end of thehandle, making the handle every way firmer and more durable andpreventsthe handle from turning on the shank. Any plastic material which can beintroduced to fill the space between the shank and the interior ofhandle which will harden and when hardened be of sufficient strength isthe equivalent of the soft metal.

I claim as my improvement-'- 1. In combination, the non-metallic handleinteriorly larger than the shank, the shank inserted through the handle,the collars on the shank at the two ends of the handle, and the softmetal or other material making contact with the exterior of the shankand the interior of the handle.

2. In combination, the hollow wooden handle interiorly non-cylindrical,the non-cylindrical shank inserted through the handle, and the softmetal or other material making contact with the exterior of the shankand the interior of the handle.

3. In combination, the shank having fiattened sides, the ferrule-collaron the shank embracing the upper end of the handle, the nut-collar onthe shank centering the lower end of the handle, the interiorly-groovedhandle, and the soft metal or other material making contact with theexterior of the shank and the interior of the handle.

In testimony whereof Iaffix my signature in presence of two witnesses.
